The proposal to the competition is based on three principles, functionality, spatial quality and environmental sustainability. These principles are the generators of volumes and voids, of the spatial characteristics of the building, of the conditions required to materials and of the approach to energy systems.
The building is simply organized, giving a clear understanding of space and circulation, so that passengers can easily move through without having to request additional information. The lobby is located above the platforms, with direct views onto the trains, thus the traveler has no doubt of where he or she is, and of where to go.
The aim has been to create an underground space having the conditions of outer space, ie, natural lighting, brightness and natural ventilation. Doing so, environmental sustainability is achieved in addition to improved environmental quality, by minimizing energy consumption of air conditioning (by means of using passive solar architecture) and lighting (reducing electricity consumption)
The transfer terminal building formally seeks a reference to the train, its speed and dynamism. The station intends to displace the passenger spatially and temporarily, transporting him or her to different time coordinates. The TGV is technology of a future that has come true, and the design of the station plays with the images of the future world that we all have in our collective subconscious. The circular capitels of the pillars, the large elliptical holes crossed by escalators, the glass floors, the curved walls,bright light and the lack of references to the outside are all elements of the classic iconography of science fiction that we have reinterpreted in this proposal.
